递归读取文件夹并在每个文件夹上执行命令 [英] Recursively read folders and executes command on each of them

问题描述

我试图递归到文件夹，然后使用bash脚本在文件夹上运行命令.有什么建议吗?

I am trying to recurse into folders and then run commands on them, using bash script. Any suggestions?

推荐答案

如果要递归到目录中，请在其中找到的每个文件上执行命令，我将使用find命令，而不是使用shell编写任何内容-脚本，我想.

If you want to recurse into directories, executing a command on each file found in those, I would use the find command, instead of writing anything using shell-script, I think.

该命令可以接收很多参数，例如type可以过滤返回的文件类型，或者exec可以对每个结果执行命令.

That command can receive lots of parameters, like type to filter the types of files returned, or exec to execute a command on each result.

例如，要查找我当前所在目录下的目录:

For instance, to find directories that are under the one I'm currently in :

find . -type d -exec echo "Hello, '{}'" \;

哪个可以让我得到类似的东西?

Which will get me somehthing like :

Hello, '.'
Hello, './.libs'
Hello, './include'
Hello, './autom4te.cache'
Hello, './build'
Hello, './modules'

可以在当前目录下找到文件:

Same to find the files under the current directory :

find . -type f -exec echo "Hello, '{}'" \;

这会让我得到这样的东西:

which will get me something like this :

Hello, './config.guess'
Hello, './config.sub'
Hello, './.libs/memcache_session.o'
Hello, './.libs/memcache_standard_hash.o'
Hello, './.libs/memcache_consistent_hash.o'
Hello, './.libs/memcache.so'
Hello, './.libs/memcache.lai'
Hello, './.libs/memcache.o'
Hello, './.libs/memcache_queue.o'
Hello, './install-sh'
Hello, './config.h.in'
Hello, './php_memcache.h'
...

有人会说不是壳"……但是为什么要重新发明轮子呢?
(从某种意义上讲，它是shell ^^)

Some would say "it's not shell"... But why re-invent the wheel ?
(And, in a way, it is shell ^^ )
